Over the next few years, the Department of Transportation is phasing out the old ORM-D classification for consumer commodities and replacing it with an expanded universe of limited quantity authorizations. In most cases, the only difference for the end-user will be replacing the rectangular ORM-D, CONSUMER COMMODITY marking with the new diamond Limited Quantity marking.
Many consumer commodity hazmats are transported in small packages, with dimensions only 4 or 6 inches wide. Because the DOT’s new limited quantity marking is larger than the older ORM-D, CONSUMER COMMODITY marking, shippers may have difficulty fitting all necessary marks and labels on smaller consumer commodity packages.
Whether the marks/labels are pre-printed or affixed at the time of shipping, it can be expensive to reorganize labels or affix them to the same side of a package to make them fit.
Hazardous Materials Administration Authorizes Reduced Marking
According to the Hazardous Materials Regulations, each limited quantity marking must be durable, legible, of a size relative to the package that is readily visible, and at least 100 mm (4 inches) on each side, unless the package size requires a reduced-size marking. [49 CFR 172.315; emphasis added]
This phrase has traditionally been interpreted by shippers to mean that reduced-size markings are authorized only when the full-sized marking will not fit on the package. In the letter of interpretation from October 1, 2012 (12-0177), however, PHSMA authorized reduced-size markings “…to the extent necessary to accommodate pre-printing of [the] additional information needed with the limited quantity marking.”
This means that you can use a reduced-size (down to 50 mm) limited quantity marking on a package, even when the full-sized (100 mm) marking will fit. This is similar to provisions that already exist in IATA 22.214.171.124. By using a reduced-size label, you can free up room for other markings to ensure you communicate all the critical information on your package in a way that’s easy for shipping personnel, carriers, and first responders to recognize and use.
